The pros of linking out
There are some reasons why a writer should consider linking out. This includes those who create web pages or articles. For SEO purposes, it is best to create links on the keywords that the article or website is focused on as this can help those keywords be found more easily when people are surfing for information.
For the reader - When a writer links out to another website readers can get more information about the subject. This provides a better reader experience by ensuring that the information they read is accurate and up to date. This also allows the reader to research the topic more thoroughly.
For the writer - While some writers are reluctant to link out, it is possible that by doing so they increase their chances of developing a new incoming link. Writers get to know each other not only by sharing a common love for writing, but by reading articles and web content that is linked to their content. The ability to increase incoming links helps with page rank.
For search engines - Although writers feel that linking out may harm them with search engines, the fact is that an outbound link helps search engines validate the subject matter of the website or the article. This means that an article that contains at least one good outbound link may have more credibility than equally well written content without a link.
Cons of linking out
As with anything else, there are downsides of creating outbound links. Although there are some pros to linking out, the writer of website content or articles must carefully weigh the pros and cons of using outbound links for SEO purposes.
For the reader - Readers can get easily distracted and if the writer creates an outbound link the reader my wander way from the site where they found your article or web content. This phenomenon can be thwarted if the outbound link is set to open in a new tab or window.
For the writer - In most cases, the writer does not benefit from outbound links. Creating an outbound link leaves some writers feeling that they must validate their work to the reader and that outbound links damage their credibility.
For the search engines - Since most search features are based on keyword searches, linking to specific keywords provides link juice to the site that the writer is linking to on their web page or article. This means that the site getting the link gets a boost in the search engines.
